The CBO report [pdf] pegs the cost of the new compromise at $871 billion, more than $20 billion more than the previous Senate bill. From the Director's Blog:
By 2019, CBO and JCT estimate, the number of nonelderly people who are uninsured would be reduced by about 31 million, leaving about 23 million nonelderly residents uninsured (about one-third of whom would be unauthorized immigrants). Under the legislation, the share of legal nonelderly residents with insurance coverage would rise from about 83 percent currently to about 94 percent. Approximately 26 million people would purchase their own coverage through the new insurance exchanges, and there would be roughly 15 million more enrollees in Medicaid and CHIP than is projected under current law. Relative to currently projected levels, the number of people purchasing individual coverage outside the exchanges would decline by about 5 million. The number of people obtaining coverage through their employer would be about 4 million lower in 2019 under the legislation, CBO and JCT estimate.
The "compromise" for the public option, the national non-profit may actually never be created, according to CBO:
The proposal would call on OPM to contract for two national or multi-state health insurance plans—one of which would have to be nonprofit—that would be offered through the insurance exchanges. Whether insurers would be interested in offering such plans is unclear, and establishing a nationwide plan comprising only nonprofit insurers might be particularly difficult. Even if such plans were arranged, the insurers offering them would probably have participated in the insurance exchanges anyway, so the inclusion of this provision did not have a significant effect on the estimates of federal costs or enrollment in the exchanges....
Replacing the provisions for a public plan run by HHS with provisions for a multi-state plan under contract with OPM is unlikely to have much effect on average insurance premiums because the existence of that public plan would not substantially change the average premiums that would be paid in the exchanges. The provisions contained in the manager’s amendment to regulate the share of premiums devoted to administrative costs would tend to lower premiums slightly, and the provisions prohibiting the imposition of annual limits on coverage would tend to raise premiums slightly.
TPM has more:
The CBO has concluded that, on average, premiums will be the same as they would have been if the Senate had the public option, but that the public option saved the federal government more money by putting downward pressure on the premiums of low-cost private plans, which will be heavily subsidized.
The bill remains a big deficit slayer--$132 billion in the first 10 years. Over the next 10 years, CBO warns all estimates are very uncertain. But here's a key conclusion: "CBO expects that the legislation, if enacted, would reduce federal budget deficits over the ensuing decade relative to those projected under current law--with a total effect during that decade that is in a broad range around one-half percent of GDP."
Update: Of special note from the CBO report--which Pelosi should be trumpeting:
[FN 11] The presence of the public plan had a more noticeable effect on CBO’s estimates of federal subsidies because it was expected to exert some downward pressure on the premiums of the lower-cost plans to which those subsidies would be tied.
